We describe the quenching behavior of thermally activated delayed fluorescence (TADF) from 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN) by O2 in bis(2-ethylhexyl)sebacate (DOS). Importantly, the high quantum yield of photoluminescence (φPL = 0.93) with efficient TADF was dramatically decreased by O2. The quenching rate constants of the S1 and T1 states were estimated to be in the order of 109 and 108 s-1 M-1, respectively. A DOS-plasticized polystyrene film containing 4CzIPN was prepared for optical O2 sensing to determine O2 concentration.
